If things like greasy dirt remain on the doors and windows, washing them with neutral cleanser. Though copper door is naturally resistant to corrosion, chemical changes will easily happen when it meets a large number of sulphur and sulphides. 5. Mind the strength when open and close the door. The strength should be even. The door itself is not easy to be damaged, but some of the mechanical parts of it may be abraded or less flexible in the process of using. Therefore, it's necessary not to open or close the door with much strength. The inflexible part can be fixed with a small amount of lubricating oil. Do NOT use too much. Then use cotton cloth to wipe off the oil to avoid dust.
